Near-Infrared Spectrophotometry of the Satellites and Rings of Uranus

New spectrophotometry from 1.5 to 2.5 /zm is reported for the Uranian satellites Titania, Oberon, and Umbriel. A spectrum of the rings of Uranus from 2.0 to 2.4/zm is also reported. No evidence is found for frost covering the surface of the ring material, consistent with the low albedo of the rings (P~ = 0.03) previously reported by Nicholson and Jones (1980). The surfaces of the satellites are...

Design of a Near Infrared Spectrophotometry Brain Imaging System

Measuring brain activity is at task generally left for EEG or fMRI. However, there is a lesser known imaging technique known as near infrared spectrophotometry, in which near infrared light is shown into the patients head to measure changes in oxygenation that directly relate to brain activity. This paper describes a low-cost, wireless, portable near infrared spectrophotometry system that is ab...

Near-infrared spectrophotometry: a new dimension in clinical chemistry.

The near-infrared (NIR) spectral region (700-2500 nm) is a fertile source of chemical information in the form of overtone and combination bands of the fundamental infrared absorptions and low-energy electronic transitions. This region was initially perceived as being too complex for interpretation and consequently was poorly utilized. Advances in chemometric techniques that can extract massive ...

Infrared spectrophotometry of enteric bacteria.

Infrared spectrophotometry is rapidly assuming an important place in the biological sciences. Its value derives from the fact that each organic compound has a characteristic and distinct infrared spectrum that can be used to identify it (Randall et al., 1949). The biologist working with cells or tissues is confronted by a highly complex mixture of substances. The infrared spectrum of a cell, th...
